- Abstract
Sorption of CH3131I from the steam-gas phase on Ag-containing zeolites modified with acetylene was studied. The radioiodine adsorption in a column depends on the silver concentration in the sorbent, humidity of the steam-gas flow, and the temperature. The modified sorbents AgX-m containing ∼30-57% silver efficiently localize CH3I at the humidity up to ∼80% and sorption temperature from 120 to 195°C. Under these conditions the decontamination factor of a gas flow with respect to CH3131I at 7.5-cm height of the sorbent bed and a ∼0.2 s gas-sorbent contact time exceeds 99.99%. The sorption properties of the modified Ag-containing sorbents are better that those of the nonmodified sorbents and known Ag-substituted zeolites.
